MOLD FOR CEMENT FENCE-POSTS AND THE LIKE.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed. May 11, 1905- Serial No. 259,880.

To all 1071/0177, it may concern:

Be it known that I, JOHN J. LUCK, a citizen of the United States,residing at Aurora, in the county of Kane and State of Illinois, haveinvented certain new and useful Improvements in Molds for CementFence-Posts and the Like; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being bad to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in molding devices for molding orforming fenceposts and like elongated articles which are molded or givenform while in a plastic state and which subsequently harden to retainthe form given thereto.

The mold herein shown is generally like that illustrated in my priorapplication for United States Letters Patent, filed April let,

'1905, Serial No. 255,638, wherein the mold consists of areceiving-shell into which the plastic material is poured and in whichit hardens and is constructed to be expanded so as to be readily removedfrom the set form, and

a confining member which holds the receiving-shell in form to receivethe plastic material and the release of which permits expansion of thereceiving-shell, as aforesaid. The receiving-shell herein shown is madeof two 'longitudinally-divided complemental parts,

which when assembled and held together by the retaining member are ofproper cross-sectional dimensions to form a post or the like to bemolded therein.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of the mold made inaccordance with my Figs. 9. and 3 illustrate separately the two membersof the receiving-shell. Fig.

4 is a perspective view of the upper end of the clamping or confiningmember for holding together the two members of the moldshell. Fig. 5 isan enlarged cross-sectional view of the assembled mold. Fig. 6 is a viewof the same parts, showing also therein the material constituting themolded fence-post and the manner of securing wire-fastening devices inthe post. Fig. 7 illustrates one form of wire-fastening device.

As shown in the drawings, the mold consists, essentially, of an uprightshell open at both ends and composed principally of two form octagonalposts or like articles which taper from their lower end to their upperends, and the member A embraces seven sides of the octagonal mold, whilethe member B is provided with one side 6, which closes the longitudinalopening a of the member A and constitutes the eighth side of theassembled octagonal mold. Said member B comprises also two angular parts6' b at each side of the part I), which lie against the correspondingparts of the member A, as shown in Fig. 5, when the mold members areassembled, so that they may be readily assembled and dismembered. Themembers A and B are held together by means of a confining or clampingmember G, that fits outside of the exposed side or part of the member Band bridges the opening in the member A. The confining or clampingmember C is provided at its longigitudinal margin with hook-flanges c,that engage complemental hook-flanges a on the margins of the member Aat the sides of the opening a thereof, as shown in Figs. 5 and 6. Whenthe mold members are tapered, as herein shown, the clamping or confiningmember C is placed in position with the hook-flanges thereof engagingthe hook-flanges of the member A, and thereafter the part C is slippeddownwardly to effect by a wedging action the bringing together of themold members to the desired or final cross-sectional dimensions. It willbe observed with reference to Figs. 5 and 6 that the side 6 of thesmaller member of the mold constitutes one of the outer faces of theassembled mold, while the other sides of the mold consist of the sevenfaces of the larger member A. The mold maybe made of othercross-sectional shapes while retaining the principle of assembling andoperation thereof shown.

Cement articles of this character are usually provided with astrengthening-core, the core D herein shown being made [VI-shaped. Suchcore is placed in the mold after the same has been assembled prior tothe pouring operation, so as to be embedded in the plastic material IIOpoured thereover, when it subsequently hardens.

When manufacturing fence posts, some means must be provided forattaching thereto the wires or other parts of the fence which the postssupport. Means are herein shown for attaching a specific form ofwire-fastening device E. (Shown in detail and separated from the otherparts in Fig. 7.) The fastening device .consists of shank portions 0 andeyes (4, when assembled in the post, the eyes projecting laterally fromthe post and are vertically separated to receive laterally in the spacebetween them a fence-wire, as the wire Gr, Fig. 7. The wire is held inplace by a pin or wire (5 inserted vertically through the eyes laterallyoutside of the fence-wire. Usually a single wire a cooperates with allthe fasteners of one post for retaining the fence-wires engaged with thefasteners of a single post. Said fastening device is made from a singlepiece of wire and is formed to constitute the upper and lower shanks a creferred to and at their outer ends the eyes a, above mentioned. Theshank members 0 of said fasteners are made of such form as to preventthe same being readily pulled out of the posts and conveniently fitwithin the spaces between the inner and outer side members of the core.As herein shown, the ends of the wire forming the fasteners are turnedoutwardly away from each other to constitute holding-prongs a", and thelooped part #of the wire is spread to constitute a like holding device.As a means of fixing said fastening devices in the posts when they aremolded one of the mold members, the side bof the member B, as hereinshown, is provided with a plurality of pairs of vertically-separatedslots 5, through which the eye portions of the fastening devices are eX-tended during the pouring operation, the shanks of said fasteningdevices extending into the interior of the mold. Said fasteners areadapted to be inserted through said openings h before the mold membersare assembled, as shown in Fig. 3. In order to hold the fasteners inproper position during the pouring operation, a rod F is preferablyextended through all of the eyes of the series of fasteners of the post,as indicated in Fig. 3. The clamping member C is arched to afford spacefor the projection of the eyes of the fastening devices from the frontface 5 of the smaller member of the mold. After the form has become setthe fastening member 0 is withdrawn upwardly from the mold members, andthe member B of the mold is drawn laterally away from the member A, soas to permit the same to be removed, notwithstanding the projection ofthe eyes of the fastening devices therethrough. The foregoingconstitutes one convenient form of fastener and means of fixing the samein the posts. It will be observed, however, that other forms offasteners may be employed and in which event the confining orclampingmember of the mold may be modified. Moreover, the posts may beformed with through-openings designed to receive fasteners in the samemanner as shown in my copending application for United States LettersPatent, Serial No. 255,638that is to say, by providing the mold memberswith registering apertures through which are passed rods to form saidopenings and which are withdrawn after the molded form has set, butbefore it has fully hardened.

The mold herein shown is designed to be operated in the same manner asare the molds shown in my aforesaid application-that is to say, arrangedupright during the pouring operation after which the molds are withdrawnand the molded forms allowed to stand in a vertical position during thesubsequent hardening process.

I claim as my invention- 1. A mold for molding fence-posts and otherelongated articles from plastic material, comprising an upright tubularmold open at both ends and consisting of two longitudinally-separated,complementally-fitted, members one of which fits partially within theother, and means engaging one of said members for confining the moldmembers together in operative position.
